This website also gives the following two alternate English translations, which are longer, rather than shorter, than the original.

The sinking moon has left the sky,
The Pleiades have also gone.
Midnight comes--and goes, the hours fly
And solitary still, I lie.

The Moon has left the sky,
Lost is the Pleiads' light;
It is midnight,
And time slips by,
But on my couch alone I lie.

See this website for, among other things, a possible Arabic translation (I don't know what the source of the Arabic translation is -- except that it's not Google translate nor Babelfish --, nor whether it's any good, since I don't speak Arabic.)_________________"We're the healthiest horse in the glue factory" - Erskine Bowles, Co-Chairman of the deficit reduction commission
